Southeast Alaska Forecast Discussion National Weather Service Juneau AK Issued by National Weather Service Anchorage AK 855 PM AKDT Fri Apr 17 2026


SHORT TERM
/Through Sunday night/ A series of fronts will continue to impact the panhandle into Saturday from a low in the northwest gulf as well as another low spinning off of Haida Gwaii. Moisture from this second low will be drawn northward into the panhandle leading to increasing precipitation for the southern panhandle Friday night into Saturday morning. Precipitation is expected to continue to remain primarily rain at sea level as snow levels range from 1000 to 2500 ft. Higher inland areas of both the Haines Highway and Klondike Highway will see some wet snow. White Pass is likely to see the highest totals, though accumulations are expected to stay below advisory level with around 2 to 3 inches during any given 12 hour period. This could also be limited due to shadowing from mountains to the southwest before the moisture transport shifts more southerly Saturday. Overall, relatively light precip is expected to continue for the start of the weekend, beginning to taper off from north to south late Saturday and into Sunday with an approaching ridge in the gulf. Some light precipitation may then ride over the northern edge of the ridge impacting the far northern panhandle and northeast coast, but model guidance has been on a downward trend as the parent feature.

Winds across the inner channels will remain relatively unchanged Friday night into early Saturday as the low off Haida Gwaii eventually stalls and then weakens while it retreats southward, with the gradient beginning to slacken across the region Saturday.
The ridge moving into the gulf from the west will also shift winds to be more westerly and then northwesterly later in the day Saturday across the gulf, though expected to top out around fresh breeze (17 to 21 kt). For more info on marine conditions this weekend, see the marine discussion below.

LONG TERM
/Sunday through Tuesday/...Rainfall rates are expected to taper off through Sunday morning before another front moves along the northern gulf coast Sunday afternoon, forcing the lingering precipitation to shift southeast out of the panhandle. Uncertainty has somewhat improved from yesterday, with models coming more in line with a potential break in rainfall Sunday afternoon before the next frontal band moves into the northeast gulf coast.
Locations near Yakutat and along the northern gulf coast will see the most rainfall with this system on Sunday, but the frontal band is expected to spread into the rest of the panhandle by Monday.
Due to the northern track of this front, precipitation has the possibility of falling as snow overnight for northern locations near Yakutat and the northern highways. Gusty winds through the outer gulf waters and into the N/S oriented channels will be present with this frontal band. High temperatures look to slightly increase through the period, though low temperatures look to stay relatively consistent around mid 30s. This front looks to push southeastward Tuesday, dragging precipitation through the central & into the southern panhandle through the rest of the period with post-frontal moist onshore- flow showery activity following behind it into the future. For Tuesday, expect an increase in WSW winds up to 35 to 40 kt gales for the southern half of the eastern gulf waters associated with the aforementioned weather system.
